Naaaah, I like much more this new engine. The first one was too much of a clone of minecraft, stuck to a grid and clunky. The last engine has some fun fun interactions between plops and objects and freedom. Imageine if you could do few steps further with both these things.

First, you would add surface smoothing, so grass, dirt and exposed rock would be smoothed but you still would have pointy stones while digging. Second, you could smooth choosen parts by hand, like sticking mortar between bricks, keeping that organicall, wonderfull look but with seamless connections.

Third, if you could do little bit more with objects like chairs, trees etc. If you could plop start of the table and then move few steps and plop its end to determinate its lenght and maybe curves you could end with EVEN MORE organic places. If you could plop beggining of the pipe and its end and corners.

Uberdark is fun for me because it tries to do something different. I don't like to be entangled by a grid T_T
